DIP Switch Setting
DIP Switch positions are defined in the table
below.
Abbreviations: CSync = Composite Sync
H = Horizontal, V = Vertical
Switch Description ON OFF ¬
1 Output Sync Polarity Negative Follow Input
2 Original/Processed Sync Original Processed
3 H/HV BNC Sync CSync H Only
4 Shift Function Disable Enable
5 Shift Mode Test Normal
6 Operating Mode Slave Master
Connecting the VS50 SL Input, Output and ShiftLock Cables
Use the diagram below as an aid to connecting input, output and
ShiftLock
TM
cables to the VS50 SL Video Shifter. The video (RGB)
cables are routed directly from the source to the destination device.
However,the sync cables must be routed through the VS50 SL as shown
in the diagram. If connecting more than one VS50 SL, the ShiftLock
TM
connectors may be connected to allow a Master/Slave setup as shown
in the upper left corner of the diagram.
VideoShift
TM
VideoShift
TM
is a technique in which the displayed video image is slowly
shifted horizontally and vertically in a clockwise (rotating) direction.
Gradually shifting the position of the video image in this manner reduces
"burn-in" damage to the CRT which can occur when intense images are
allowed to remain in the same position for extended periods.
ShiftLock
TM
ShiftLock
TM
is a feature that enables synchronization of the VideoShift
TM
capability of two or more devices. Input and output ShiftLock
TM
connectors
allow VideoShift
TM
devices to be connected (daisy-chained) enabling the
"Master" device to control VideoShift
TM
for itself and all "Slave" devices.
VS50 SL Operation
The model VS50 SL Video Shifter includes both VideoShift
TM
and
ShiftLock
TM
features. The operating characteristics of the VS50 SL are
controlled by the position of the six switches on the DIP switch module.
The DIP switches are externally accessible and the switch positions are
briefly defined in the table on the facing page. The following descriptions
and specifications are provided as an aid to understanding the operating
mode of the VS50 SL as a function of the DIP switch settings.
1. Original Sync Mode (DIP switch 2 (SW2) = ON):
A. When set for separate H&V out (SW3 = OFF):
a. If input = separate H&V,
H/HV out = H in,V out = V in
b. If input = composite sync (CS),
H/HV out = CS in, V out = V stripped from CS in
B. When set for Composite Sync out (SW3 = ON):
a. If input = separate H&V,
H/HV out = Composite sync, V out = Gnd
b. If input = Composite sync,
H/HV out = CS in, V out = Gnd
2. Processed Sync Mode (SW2 = OFF):
A. When set for separate H&V out (SW3 = OFF):
H/HV out = H processed, V out = V processed
B. When set for CS out (SW3 = ON):
H/HV out = Composite sync, V out = Gnd
3. Output sync polarity:
A. Output sync is negative when CS output selected (SW3 = OFF)
B. Output sync is negative when Negative sync selected (SW1 = ON)
C. Follow input polarity when Follow Input is selected (SW1 = OFF)
(Note: For CS input, both H&V sync will be negative)
4. Processed sync timing specifications:
A. Delay from original sync (Shift Function = disable [SW4 = ON]):
75 micro-seconds for Vertical Sync
310 nano-seconds for Horizontal Sync
B. Shifting range (from Shift Function = enable position [SW4 =OFF]):
±20 micro-seconds for Vertical Sync
±25 nano-seconds for Horizontal Sync
5. Shift timing specifications:
A. Shift Mode = Test (SW5 = ON) = 4 seconds/rotation
B. Shift Mode = Normal (SW5 = OFF) = 5 minutes/rotation
